Alloy question

[MAcle1997]

I was just contacted by a guy who lost his wedding ring in his yard while raking leaves
last fall. I figured that it would be pretty easy to find since it was lost recently and the
weather here in Western New York has been pretty mild this winter. The problem is
that he says the ring was an alloy of cobalt, chromium and molybdenum.
Does anyone have any idea how an alloy of those metals would show up on an
Explorer II? I'll probably use Iron Mask -16 and since I don't want to miss anything.
I'll try both ferrous and conductive sounds and see what works better. The yard isn't
very large and I can go back in the spring/summer if necessary.

Thanks for any help you can provide.

Well,

Those alloys are common additives to austenitic stainless steel. I havent dug any stainless alloys (or have and can't remember) so I have no idea where it would come up. My initial guess would be between mid scale to upper middle of the screen. If you have a 316 ss piece of similar size that should get you ball park in the area, also high consentration cobalt drill bits is another test option. Good luck and

HH,

I have found 2 rings that are close to what your looking for. I just ran them both over my coil and in an air test they came up as 11-03 and 10-05. Mind you, thats in an air test but hopefully this will help you in some way. Also, being that the ring will probably not have sunk far (being very light), you might want to start with your sensitivity very low and only check shallow targets that are in the foil range. Let us know if you find it. HH -Marc

I hope to get out tomorrow afternoon for a few hours and cover the target area
at least once. Hope the weather will cooperate.

Good luck finding it. Please let me know if you found it, and if so, what the TID was. HH -Marc

I find a lot of the SS on the beach.... they read very low from 11-01 to about 11-05 depending on the size, density, and position of the ring.

I went out this afternoon and found that wedding ring under a pile of leaves
in the front yard. I was using and Explorer II, Iron Mask at -9 and conductive
sounds. I used the Sunray X-5 coil with a sensitivity of 20. The ring was
laying flat under the leaves and buried in the mud with just the top edge
showing after I brushed the leaves away. Target IDs were 11-00 and 10-01.
I also found several nails, bottle caps a pull tab and a stainless steel serving
spoon at five inches deep.
This couple has been married for a year and were
surprised to see that I had found the ring so quickly. I got permission to come
back any time until the move in June to search the rest of the yard. Thanks for
the help with the ID numbers.
